4.1.1 Step 1.1: CH - Children’s Recode (Under 5)

According to the STATA do file there is no data for this section.

4.1.2 Step 1.2: BH - Birth Recode (All females 15-49 years who ever gave birth)

The purpose of step 1.2 is to identify children of any age who died in the last 5 years prior to the survey date. As seen in the STATA file

Loading the data from bh.sav.

bh_dat <- read_sav(file = here("Viet Nam_MICS5_Datasets",
                     "Viet Nam MICS 2013-14 SPSS Datasets",
                     "bh.sav"))

bh_dat <- clean_names(bh_dat)

The above code chunk loads the bh.sav and names it bh_dat(a data object). The clean names function gets all the variable names in lower snake case. IN case if anyone is wondering what are all the possible cases, please refere to the wonderful art by Allison Horst shown below.

Various Cases (Let me know your favourite)

Now let us take a glimplse at the data and names of the variables.

names(bh_dat)

##  [1] "hh1"       "hh2"       "ln"        "bhln"      "bh2"       "bh3"      
##  [7] "bh4m"      "bh4y"      "bh5"       "bh6"       "bh7"       "bh8"      
## [13] "bh9u"      "bh9n"      "bh10"      "bh4c"      "bh4f"      "bh9c"     
## [19] "bh9f"      "hh6"       "hh7"       "wdoi"      "wdob"      "ethnicity"
## [25] "welevel"   "brthord"   "magebrt"   "birthint"  "wmweight"  "wscore"   
## [31] "windex5"   "wscoreu"   "windex5u"  "wscorer"   "windex5r"  "windex2"

head(bh_dat) %>% gt()

Now let us create variables, only those that are non grouped, i.e. those generated without using bysort. In R one can create grouped varibales in a different manner. Will show that in the code chunk following this one.

Before moving forward, please note that, a large part of coding involved in creating this index is a data wrangling process. The tidyverse way of carrying out data wrangling extensively employs {dplyr} (read as ‘package dplyr’) and its mutate function. Here is a visual cue (created by Allison Horst) to what the mutate function does.

Wrangling and adding columns

bh_dat <- bh_dat %>% 
  mutate(
    ind_id = structure(((hh1*100000)+(hh2*100)+ln),
                       label = "Individual ID"),
    date_death = structure(bh4c + bh9c, 
                           label = "Date of Death CMC"),
    mdead_survey = structure(ifelse(((bh9c == 0 |is.na(bh9c)) & bh5 == 1),
                                     NA, 
                                     wdoi - date_death), 
                             label = "Months Dead from Survey"),
    ydead_survey = structure(mdead_survey/12, 
                             label = "Years dead from Survey"),
    age_death = structure(ifelse(bh5 == 2, bh9c, NA),
                          label = "Age at death in Months"),
    child_died = structure(forcats::as_factor(
      ifelse(is.na(bh5),NA,
             ifelse(bh5==1,"child is alive","child is dead"))))
    ) %>% 
  group_by(ind_id) %>% 
  mutate(
    tot_child_died = sum(child_died == "child is dead", na.rm = T)
  ) %>% 
  ungroup() %>% 
  mutate(
    child18_died = forcats::as_factor(
      ifelse((!is.na(age_death) & age_death > 216),
             ifelse(is.na(bh5),NA,
                    ifelse(bh5==1,
                           "child is alive",
                           "child is dead")), 
             "child is alive"))
    ) %>% 
  group_by(ind_id) %>% 
  mutate(
    tot_child18_died_5y = sum(
      child18_died[ydead_survey <= 5 & !is.na(ydead_survey)] == "child is dead", na.rm = T)
  ) %>% 
  ungroup() %>% 
  mutate(
    tot_child18_died_5y = ifelse(
      (is.na(tot_child18_died_5y) & tot_child_died>=0 & !is.na(tot_child_died)),0,tot_child18_died_5y),
    tot_child18_died_5y = ifelse(
      child18_died == "child is dead" & is.na(ydead_survey), 
      NA, tot_child18_died_5y)
  ) %>% 
  group_by(ind_id) %>% 
  mutate(
    childu18_dies_per_wom_5y = structure(
      max(tot_child18_died_5y,na.rm = T),
      label = "Total child under 18 death for each women in the last 5 years (birth recode)")
  ) %>% 
  ungroup()

Check if all ind ids are uniuqe

nrow(bh_dat) == length(unique(bh_dat$ind_id))

## [1] FALSE

There are duplicate ind_ids. Let us remove duplicates.

bh_dat %>% distinct(ind_id,.keep_all = TRUE) -> bh_dat

Check again if all ind ids are uniuqe

nrow(bh_dat) == length(unique(bh_dat$ind_id))

## [1] TRUE

Creating Tables for new variables check.

bh_dat %>% 
  tabyl(age_death,show_na = TRUE) %>% 
  gt() 

bh_dat %>% 
  tabyl(bh5, child_died, show_na = T) %>% 
  gt()

bh_dat %>% 
  tabyl(child18_died, show_na = T) %>% 
  gt()

bh_dat %>% 
  tabyl(tot_child_died, tot_child18_died_5y, show_na = T)

##  tot_child_died    0 1
##               0 6647 0
##               1  382 7
##               2   55 0
##               3    6 2
##               4    2 0

Writing new files.

write_csv(bh_dat,here("output data files","1.2VNM14_BH.csv")) # same as VNM14_BH.dta

4.1.3 Step 1.3: WM - Women’s Record (All eligible females 15-49 in the household)

Loading data and setting case for variable (column) names.

wm_dat <- read_sav(file = here("Viet Nam_MICS5_Datasets",
                     "Viet Nam MICS 2013-14 SPSS Datasets",
                     "wm.sav"))

wm_dat <- clean_names(wm_dat)

Mutating the data for creating new variables. This is what one would refere to generating new varibles in STATA, I think.

Note, for the varible marital or marital_wom, I miss to see whyn the STATA code defines it as marital to begin with and renames it to marital_wom. I will define this varibale as marital_wom from the begining itself. Kindly bring to notice if this is incorrect.

wm_dat <- wm_dat %>% 
  mutate(
    ind_id = structure(((hh1*100000)+(hh2*100)+ln),
                       label = "Individual ID"),
    women_wm = 1,
    marital_wom = structure(
      forcats::as_factor(
      case_when(
        mstatus == 3 & is.na(ma6) ~ "Never Married",
        mstatus == 1 & is.na(ma6) ~ "Currently Married",
        mstatus == 2 & ma6 == 1 ~ "Widowed",
        mstatus == 2 & ma6 == 2 ~ "Divorced",
        mstatus == 2 & ma6 == 3 ~ "Seperated/Not living together",
      )
    ), label = "Marital Status of Household Member"
  )
) 

While creating new variables the STATA code has various tables. I will generate those here.

length(unique(wm_dat$ind_id)) == nrow(wm_dat)

## [1] TRUE

This means all Individual Ids are unique, i.e., every row represents a unique individual.

wm_dat %>% 
  tabyl(cm1, cm8,show_na = TRUE) %>% 
  gt()

head(wm_dat[,c("mstatus","ma6")],10)

## # A tibble: 10 x 2
##                           mstatus       ma6
##                         <dbl+lbl> <dbl+lbl>
##  1 1 [Currently married/in union]        NA
##  2 1 [Currently married/in union]        NA
##  3 1 [Currently married/in union]        NA
##  4 3 [Never married/in union]            NA
##  5 3 [Never married/in union]            NA
##  6 3 [Never married/in union]            NA
##  7 3 [Never married/in union]            NA
##  8 1 [Currently married/in union]        NA
##  9 1 [Currently married/in union]        NA
## 10 3 [Never married/in union]            NA

wm_dat %>% 
  tabyl(mstatus, ma6,show_na = TRUE) %>% 
  gt()

wm_dat %>% 
  tabyl(marital_wom, show_na = TRUE) %>% 
  gt()

wm_dat %>% 
  tabyl(ma6, marital_wom, show_na = TRUE) %>% 
  gt()

wm_dat %>% 
  tabyl(mstatus, marital_wom, show_na = TRUE) %>% 
  gt()

Keeping relevant columns.

wm_dat <- wm_dat%>% 
  select(wm7, cm1, cm8, cm9a, cm9b, 
         ind_id, women_wm, dplyr::ends_with("_wom"))

Writing the tables in csv.

write_csv(wm_dat,here("output data files","1.3VNM14_WM.csv"))

4.1.4 Step 1.4: MR - MEn’s Recode (All eligible men in the household)

As mentioned in the STATA code, Note: There is no male recode file for Viet Nam MICS 2014. Hence the commands under this section have been remove

4.1.5 Step 1.5 HH - Household Record (All Households intereviewed)

Load data.

hh_dat <- read_sav(file = here("Viet Nam_MICS5_Datasets",
                     "Viet Nam MICS 2013-14 SPSS Datasets",
                     "hh.sav"))

hh_dat <- clean_names(hh_dat)

Creating new variables.

hh_dat <- hh_dat %>% 
  mutate(
    hh_id = structure((hh1*100 + hh2), label = "Household ID")
  )

write data in csv.

write_csv(hh_dat,here("output data files","1.5VNM14_HH.csv"))

4.1.6 step 1.6: HL - Household Member

Load data.

hl_dat <- read_sav(file = here("Viet Nam_MICS5_Datasets",
                     "Viet Nam MICS 2013-14 SPSS Datasets",
                     "hl.sav"))

hl_dat <- clean_names(hl_dat)

Creating new variables.

hl_dat %>% 
  mutate(
    hh_id = structure(
      (hh1*100) + hh2,
      label = "Household ID"
    ),
    ind_id = structure(
      (hh1 * 100000) + (hh2 * 100) + hl1,
      label  = "Individual ID"
    )
  ) -> hl_dat

4.1.7 Step 1.7: Data Merging

Unlike the STATA code the merging here will look a little different. It will be in a single flow. However, checks will be shown prior to mrunnig the merge command.

hl_dat %>% 
  left_join(bh_dat, by = c("ind_id" = "ind_id")) %>% 
  left_join(wm_dat, by = c("ind_id" = "ind_id")) %>%
  tabyl(hl7, show_na = T)

##  hl7     n      percent
##    0 29190 0.7412392077
##    1  1065 0.0270441849

##   13     2 0.0000507872
##   15     1 0.0000253936

hl_dat %>% 
  left_join(bh_dat, by = c("ind_id" = "ind_id")) %>% 
  left_join(wm_dat, by = c("ind_id" = "ind_id")) %>%
  mutate(temp = hl7 > 0) %>% 
  tabyl(women_wm, temp, show_na = T)

##  women_wm FALSE  TRUE
##         1     0 10190
##        NA 29190     0

hl_dat %>% 
  left_join(bh_dat, by = c("ind_id" = "ind_id")) %>% 
  left_join(wm_dat, by = c("ind_id" = "ind_id")) %>%
  mutate(temp = hl7 > 0) %>% 
  filter((temp == 1 & is.na(women_wm))) %>% 
  tabyl(wm7, show_na = T)

## [1] wm7     n       percent
## <0 rows> (or 0-length row.names)

hl_dat %>% 
  left_join(bh_dat, by = c("ind_id" = "ind_id")) %>% 
  left_join(wm_dat, by = c("ind_id" = "ind_id")) %>%
  left_join(hh_dat, by = c("hh_id" = "hh_id")) %>% 
  filter(hh9 ==1) %>% # keeping only households that completed interview
  mutate(
    marital_men = structure(NA, label = "Marital Status of household member")
  ) -> merged_dat

Writing this object for safe keeping.

write_csv(merged_dat,here("output data files","1.7VNM14_merged.csv"))

4.1.8 Step 1.8: Control Variables

Comments from the STATA code:

Households are identified as having ‘no eligible’ members if there are no applicable population, that is, children 0-5 years, adult women 15-49 years or adult men. These households will not have information on relevant indicators of health. As such, these households are considered as non-deprived in those relevant indicators.

As one must have noticed from previous sections, I prefer not to gererate variables that are grouped in the same data frame. However, in the following sections I will follow as the code in STATA do file. This is because the code seems to mutate the same data frame starting from section Step 1.6.

Having said this, I should explain why I am averse to this practice. Consider the following example.

tibble::tibble(
  a = c(1,2,3,4,5,6),
  b= rep(letters[1:3],2)
) -> data_example ## data for illustration

data_example

## # A tibble: 6 x 2
##       a b    
##   <dbl> <chr>
## 1     1 a    
## 2     2 b    
## 3     3 c    
## 4     4 a    
## 5     5 b    
## 6     6 c

Say, we want sum of column a for each type of observation in column b. We shall name this new variable c.

data_example %>% 
  group_by(b) %>% 
  mutate(
    c = sum(a)
  )

## # A tibble: 6 x 3
## # Groups:   b [3]
##       a b         c
##   <dbl> <chr> <dbl>
## 1     1 a         5
## 2     2 b         7
## 3     3 c         9
## 4     4 a         5
## 5     5 b         7
## 6     6 c         9

Above is the output we would generate if we wanted a sum of ‘a’ grouped by ‘b’. This might end up being misleading to someone who has neve seen the code but want to use the data. Some might do a simple average of cloumn c or try other summary statistics over this new column.

Moving on.

4.2.1 Step 2.1: Years of Schooling

Comments from the STATA Code:

Note: In Viet Nam, children enter primary school aged 6 years, enter lower secondary school at 11 and upper secondary school at 15. There are grades in primary school (Grades 1 to 5), four in lower secondary school (Grades 6 to 9) and three in upper secondary school (Grades 10 to 12).(pg 192 report)

Let us first save the data frame created in the environment. This way we reduce the length of the code and copy pasting it again and again.

Now, I feel it is as good a time as any, since we have moved this forward in to mutating new variables, to introduce the {magrittr} pipes. Up till now in the document you must have seen %>% appear everywhere. This is a pipe operator. What it does is to allow us to write code where the format is similar to f(g(y(x))), where f,g, and y are function, and x is input for y and y(x) is input of g and so on.

One must have noticed that if I am mutating multiple varibables of a data frame I ahve to reassign the mutated data frame with -> or <- operator. This can be redundant at times. Consider the following example.

tibble(
  a = c(1,2,3,4),
  b = c(11,22,11,11)
) -> ex_pipe

let us say I want a new variable c = a*b in the same data frame ex_pipe and keep rows where b is 11. Below is code to do it with using pipe operator.

ex_pipe %>% 
  mutate(
    c= a * b # creating new variable
  ) %>%  # using pipe to feed the output of mutate in to filter function
  filter(
    b == 11
  ) -> ex_pipe # updating the ex_pipe object/ data frame by reassigning.

I might not want to use -> operator as it can get redundant. There is a cousin of the %>% operator that helps us tackle this problem. For instance, say i want ot add 1 to c in each row and update the data prame ex_pipe.

ex_pipe %<>% ## Notice the difference
  mutate(
    c = c+1
  ) ##notice no need for arrow opration and reassignment 

ex_pipe

## # A tibble: 3 x 3
##       a     b     c
##   <dbl> <dbl> <dbl>
## 1     1    11    12
## 2     3    11    34
## 3     4    11    45
